A term originating in the philosopher Peter Suber's essay Logical Rudeness. What Suber calls logical rudeness is a response to criticism which insulates the responder from having to address the criticism directly. Suber comes up with a taxonomy of logical rudeness:
Suber goes on to say that rudeness does not imply falsehood, and in fact, to insulate yourself from criticism on the grounds that your opponent is rude is itself rude. He goes on to examine the competing norms of debate: we might wish to allow people freedom to hold to theories, including those which are rude, but we also wish debates to move forwards.
